Description

Technical Field

[0001] This invention relates to the field of cosmetics, and more particularly to a cosmetic functional anti-aging microcapsule composition and its preparation method. Background Technology

[0002] Microencapsulation technology significantly enhances the functionality and stability of cosmetics by encapsulating active ingredients in a capsule structure. Its core functions include: (1) Protecting sensitive ingredients: Many functional ingredients in cosmetics (such as vitamin C, retinol, and plant essential oils) are easily degraded by light, heat, oxygen, or pH changes; microencapsulation forms a barrier through physical isolation, extending the shelf life of the ingredients. (2) Precisely controlling release: Microcapsules can be designed for sustained release or stimulus-responsive release. The sustained release mechanism is controlled by the porosity of the polymer wall material, allowing the active ingredients to act continuously on the skin surface; the stimulus-responsive mechanism can achieve targeted release. (3) Improving sensory characteristics: Some active ingredients (such as plant extracts and sunscreens) may have unpleasant odors or textures. Microencapsulation can mask odors and optimize the skin feel. (4) Enhancing bioavailability: Microencapsulation can promote transdermal absorption through nanoscale structures; for example, the transdermal absorption rate of vitamin E encapsulated in liposomes is significantly improved.

[0003] Solid microcapsule products face challenges in compatibility with their application environment, exhibiting difficulties in dispersion or uneven dispersion within cosmetic matrices. Liquid microcapsule compositions, due to the presence of solvents and other components, are easier to disperse in cosmetic matrices and more convenient to use; however, these compositions suffer from instability. Therefore, providing a stable and highly effective liquid microcapsule composition is a key technical problem that needs to be solved. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a cosmetic functional anti-aging microcapsule composition and its preparation method.

[0031] The beneficial effects of this invention are as follows:

[0032] This invention uses water, sodium alginate, retinol, compound plant extracts, triglyceride (ethylhexanoate), and stabilizers to prepare a composition. The composition prepared from the above-mentioned active ingredients, such as moisturizing, anti-aging, and anti-inflammatory ingredients, has excellent anti-aging and anti-inflammatory functions, can effectively moisturize the skin, and has strong stability, effectively resisting the adverse effects of temperature environment.

[0033] The extract obtained by heating and stirring with water, enzymatic hydrolysis with cellulase and papain, extraction with an extractant and post-treatment can effectively inhibit the expression of inflammatory factors and has a good anti-inflammatory effect.

[0034] This invention uses both Pteris mutilida and pine bark as raw materials, which is more effective than using only one. The active ingredients of the two complement each other, enhancing their anti-inflammatory properties. The combination of chloroform and ether in the extraction solvent has a significant impact on the anti-inflammatory effect of the extract. Extracts obtained by using either one alone have poor anti-inflammatory properties, and when using both as the organic phase for extraction, the extract with a ratio of 1:0.6-1 shows better anti-inflammatory properties.

[0035] The composition prepared by this invention using water, sodium alginate, retinol, compound plant extracts, triglyceride (ethylhexanoate) and stabilizers has a high ZETA potential value, good system stability, and strong resistance to environmental challenges.

[0036] This invention selects sodium octenyl succinate starch and sodium di(lauryl ether-7) citrate as stabilizers, which can significantly improve the stability of the composition. The combination of sodium octenyl succinate starch and sodium di(lauryl ether-7) citrate in this invention has a complexing effect, significantly improving the stability of the composition, and the stability is even better when the ratio of the two is 1:2-3.5.

[0051] The extracts obtained in Examples 1-9 above were tested. The anti-inflammatory properties of the extracts were characterized by inhibiting the expression of inflammatory factors TNF-α and IL-1α using a lipopolysaccharide (LPS)-induced RAW264.7 macrophage inflammation model.

[0052] RAW264.7 cells were cultured at 7.5 × 10⁻⁶. 5Each sample was seeded in a 12-well plate with 2 mL of culture medium per well and incubated at 37°C and 5% CO2 for 24 h. The supernatant was removed, and the following dosages were applied to the controlled groups: Model group: 5 μg / mL lipopolysaccharide + culture medium to 2 mL; Blank group: culture medium to 2 mL; Positive control group: 5 μg / mL lipopolysaccharide + 200 μg / mL dexamethasone + culture medium to 2 mL; Extract group (Examples 1-9): 5 μg / mL lipopolysaccharide + 0.1 wt% extract from Examples 1-9 + culture medium to 2 mL. Each group was repeated in triplicate. The plates were then incubated at 37°C and 5% CO2 for another 24 h. The supernatant was collected, and the expression levels of TNF-α and IL-1α were measured according to the kit instructions. Results are shown in Tables 1-2 and 1-3. Figure 1-2 .

[0056] Table 2: Inhibition rate of each group compared to the model group

[0057]

[0058]

[0059] Combined with Table 1-2 and Figure 1-2 The results show that the extract obtained by the present invention through water heating and stirring, enzymatic hydrolysis with cellulase and papain, extraction with an extractant, and post-treatment can effectively inhibit the expression of inflammatory factors and has a good anti-inflammatory effect. A comparison of Examples 1-2 and 3-4 shows that using both Pteris mutilida and pine bark as raw materials is more effective than using only one, as their active ingredients complement each other and enhance the anti-inflammatory properties. A comparison of Examples 1-2 and 5-9 shows that the combination of chloroform and ether in the extractant of the present invention has a significant impact on the anti-inflammatory effect of the extract. Extracts obtained by using either one alone have poor anti-inflammatory properties, and when using both as the organic phase for extraction, the extract has better anti-inflammatory properties when the ratio of chloroform to ether is 1:0.6-1.

[0060] II. Preparation and Testing of the Composition

[0061] The composition of the raw materials of the composition is shown in Table 3; wherein, λ is the weight ratio of sodium octenyl succinate starch and sodium di(lauryl ether-7) citrate, compositions 1 and 3-7 use the compound plant extract of Example 1, and composition 2 uses the compound plant extract of Example 2.

[0062] Table 3: Composition of the composition

[0063]

[0064]

[0065] The preparation method of the above composition is as follows:

[0066] (1) Heat water to 45°C, add sodium alginate, stabilizer (sodium octenyl succinate starch, sodium di(lauryl ether-7) citrate) and phenoxyethanol, stir at 120 rpm for 20 minutes to obtain the aqueous phase;

[0067] (2) Heat the triglyceride (ethylhexanoate) to 37°C, add retinol and compound plant extract, stir at 120 rpm for 15 minutes to obtain the oil phase;

[0068] (3) Slowly pour the oil phase into the aqueous phase, keep it at 35°C and shear emulsify at 800 rpm for 20 minutes, stop shear emulsification, and let it cool naturally to room temperature to obtain the composition.

[0069] The stability of the above composition was tested to measure the ZETA potential and its rate of change. The ZETA potential characterizes the stability of the composition, while the rate of change characterizes its ability to withstand environmental challenges. The specific test method was as follows: the above composition was mixed with deionized water at a weight ratio of 1:100, stirred at 800 rpm for 30 minutes at 35°C, and then allowed to cool naturally to room temperature. The ZETA potential ζ1 was measured. The sample was then stored in a sealed container at 35°C for 3 days, and the ZETA potential ζ2 was measured again. Each group was tested in triplicate. The rate of change of ζ was then calculated as δ = |(ζ2-ζ1) / ζ1|. A larger absolute value of ζ indicates a more stable system, while a smaller value of δ indicates a stronger ability to withstand environmental challenges. Specific results are shown in Table 4 and... Figure 3 .

[0072] According to Table 4 and Figure 3 Tests show that the composition prepared by the present invention using water, sodium alginate, retinol, compound plant extracts, triglyceride (ethylhexanoate) and stabilizer has a high ZETA potential value, good system stability, and strong resistance to environmental challenges.

[0073] A comparison of compositions 1 and 7 shows that the selection of sodium octenyl succinate starch and sodium di(lauryl ether-7) citrate as stabilizers in this invention significantly improves the stability of the compositions. Furthermore, a comparison of compositions 1, 3-6 shows that the combination of sodium octenyl succinate starch and sodium di(lauryl ether-7) citrate is more effective than either alone, exhibiting a complexing effect and significantly improving the stability of the compositions, with even better stability observed at a ratio of 1:2-3.5.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; any deductions or substitutions made by those skilled in the art without departing from the concept of the present invention are within the protection scope of the present invention.
